Collector for yarn bobbins



United States Patent "ice COLLECTOR FOR YARN BOBBINS Walter Schweiter,Horgen, Switzerland, assignor to Maschinenfabrik Schweiter A. G.,Horgen, Switzerland, :1 Swiss company The present invention relates to acollector device for yarn bobbins.

In the case of known collectors of this type the bobbins ejected fromthe winding frame fall from above into the collector, whereby the yarncoils are often damaged owing to the fact that the bobbins fall on topof one another.

The present invention has as one of its objects to provide meansaifording elimination of this drawback. The invention thereforecontemplates means disposed at the lower part of the collector or itsbottom constituting a bobbin filling hole which closes automatically. Inthis way the number of bobbins in the collector can be easilyascertained and the bobbins can be taken out of the said collector fromthe side. The collectors can be secured to a loom so that the weaver canremove the bobbins from the collector, when filled, and charge the drummagazine of an automatic loom,

A typical example of the invention is illustrated in the attacheddrawing. In the drawing:

Fig. 1 shows the collector seen from the open side;

Fig. 2 is a side view of Fig. 1;

Fig. 3 is a top view of Fig. 1;

Fig. 4 is a fragmentary section, on an enlarged scale, through a portionof the bottom of the collector along the line II in Fig. 3;

Fig. 5 is a view of the shut-off fiaps along the line IL-II in Fig. 4;

Fig. 6 is an alternative example of the invention in whichthe bobbinfilling hole is arranged above the bottom plate in a side wall.

The collector consists of three perpendicular side walls 1, 2 and 3, atop 4 and a bottom plate or wall 5, together defining an open space forstorage of bobbins. To the bottom plate 5 is secured an upwardlydirected sheet metal stirrup or arcuate guide 8 which possesses cut-outportions 8a. A pivot forming rod 9 is enveloped by the remaining freesheet metal ends 8b and secured with a cotter pin. Tongues 10a of a stopplate 10, which tongues are also rolled about rod or pivot 9 and securedto the said rod with a pin, engage into the cut-out portions 8a. Thestirrup 8 and the stop plate 10 can also be made from one piece.Furthermore, the stirrup 8 possesses cut-out portions 80 in whichshut-off flaps 12 engage which are swivelly located on the rod 9. Theseshut-off flaps possess a recess 13 in which a torsion spring 14 islocated on the rod 9. One end of the said spring thrusts against thewall 12a of the shut-off flap 12' and the other against the stop plate10. The shut-off flaps 12 are pressed by these torsion springs into theposition illustrated in Fig. 4. Adjacent to the opening or aperture 5ain the bottom plate 5 there is a perpendicular web 7 which is bent overy, 2,873,063 Patented Feb. 10, 1959 from falling out by the shut-offflap 12 which at least partly obstructs aperture 5a.

It will be noted that the stirrup 8, the web 7 and the flaps 12, attheir portions facing toward the storage space, form object deflectingmeans, i. e. means which facilitate the removal of bobbins out of thefeeding path and into the storage space. Moreover, they prevent that anobject fed along said path jams the flaps 12 in closed position thereofby preventing said object from contacting the upper or inner side ofwalls 12a of the flaps 12. The defleeting means, provided by the stirrup8 and the web 7 extend into the storage space laterally of said guidechannel.

The hole through which the bobbins pass into the collector is arrangedat right angles to the rear wall 3 so that the number of bobbins in thecollector can be seen from the front and the bobbins can be easily takenout of the collector. The bobbin collector is conveniently provided withtwo handles 17 and 18 one of which is arranged in the extension of thebottom plate 5 on the open side of the collector and the other on thecollector at its top and, for the purpose of stiffening it, is securedtop 4. Owing to this arrangement of the handles the bobbins lie upagainst the rear wall of the collector so that the latter cannot becarried in such a way that the bobbins fall out, since the open side ofthe collector always faces upwards. The collector top 4 is, in addition,provided with an opening 19 which is designed for the purpose ofenabling a feeler from the winding frame to penetrate into the box,which feeler stops the delivery of bobbins when the box is full.

As Fig. 6 shows, the bobbins, in an alternative arrangement, can also befed into the collector immediately above the bottom plate through anopening in a side wall 20!, inside which shut-off flaps 12b arearranged. The bobbins 15 can be pressed into the collector by a swivelarm 16. This arrangement can be used when it is impossible, owing tolack of space, to charge the bobbins through the bottom plate.

Various changes and modifications may be made without departing from thespirit and scope of the present invention and it is intended that suchobvious changes andmodifications be embraced by the annexed claims.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent, is:
